Railway
Station: Building 3D Models Using AutoCAD
and 3D Studio Max
This
tutorial will be useful for all of you
who are trying to create a 3d model from
a real model pursuing to have precise
measurements. Our approach will be to
create a model of a railway station. So
here are 2 photos of the mentioned station.

Drawing
in AutoCAD
After
measuring comes the time to draw the different
orthographic views in AutoCAD. It is good
also to dimension all the parts to be
sure that we have drawn them correctly.
When working with AutoCAD, keep on mind
that closed splines should be easily extruded
in 3D Studio Max. As much as precise you
will be in AutoCAD as little reediting
of the splines you will need in 3D Studio
Max. I am a new user of AutoCAD, so be
merciful and patient when using my *.dwg.
It needs some postproduction, but it was
more efficient for me to do it in 3D Studio
Max.

Work
in 3D Studio Max.
a.
Import *.dwg file
b. Completely replace current scene
c. Set AutoCAD DWG file Window as shown
below.
Fine-tuning
the Splines
a.
Select all groups, open them, select
all splines and convert them to editable
spline
( this will correct the bounding boxes
of the splines ) then close the groups
b. Hide all the groups except one and
do the next with all of them
c. Some post process of splines is necessary
- attaching belonging parts, welding
overlaying vertices and etc.
Hint:
Attach the splines for windows and window
shutter, this should avoid you from
some Boolean operations after extruding
the splines
From Splines to Model
a.
Extrude the main walls
b. Extrude the details, windows and
doors
c. Duplicate the windows and doors,
hide duplicates
d. Split objects using boolean / split
( results of subtraction was not always
as desirable )
e. Delete unnecessary polys, remove
unnecessary edges and points
f. Move and detach the windows polys
g. Extrude holes
h. Unhide and fit hidden duplicates
of doors and windows
i. Detach and Attach polys to different
object corresponding to same materials
j. Assign materials
k. Render
Modeling
Animation
And
after all of this we have a precise 3D
model of railway station.
